Started Ta#47 heating at Evap2 using the autoramp program. The TGHT current is setup to go to 300A (for now) and the TBHT to 230A (final value).

One thermocouple was not welded on correctly and is not working.
Cooling evap2 back down, to remove target and re-weld thermocouple.
Once thermocouple replaced, will ramp back up and continue with tests/ conditioning of target.

After EVAP2 was vented the thermocouple problem was fixed: it was the wire at on connector inside the box not making proper contact. The lid of the heat shield was also replaced since the one initially mounted had no holes, so one couldn't see the center block. Restarted pumping down at 4:30pm. Just started again the autoramp program: TGHT set to 300A (for the time being) and TBHT to 230A. Temperature measurements will resume tomorrow morning.
|
Raised the TGHT at 620A. The TBHT was already set at 230A. The temperature is at 1902 deg C. As per John's instructions the target will condition at these setpoints over the week-end.
|
Today, lowered the TGHT from 620A (at 1894 deg C) to 300A. TBHT is still at 230A.
|
Cooling down the target.

Target was removed from the Evaporator.
The thermocouples broke off.
Need to insert Re foil prior to installing
